In the 33 years that Warhammer 40,000 has been filling dining room tables with green-skinned cockney aliens and colourful, massive-shouldered Space Marines, the setting has generated at least 50 digital game adaptations (including, latterly, a few mobile offerings) and the vast majority of those – to put it diplomatically – have not managed to capture the magic of the tabletop game or its deep fiction. Warhammer 40k computer games get a bad rap.
